Gases take the shape of their container. When you have a large container, the spaces between molecules (particles) can be further apart than if they were close together. In small containers, the particles are forced to be closer together, or compressed.
Think of it like a pep rally in a gym v.s. a classroom. In the gym, everyone has a bit of wiggle room. With the same number of people in a classroom, everyone would need to be packed in there. This can also explain why a smaller pot over boils from steam before a larger one does, even if the amount of water is the same.
If it is cooled the motion of the particles decreases as they lose energy.

-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:
- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.
- it trashes body waste and toxins (like i said above)
- it gives us nutrients and minerals
- it helps us to maintain out blood pressure
- it also helps to regulate our body temperature
- it transfers oxygen through the whole body
- it helps with digestion
- weigh loss
- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)
-prevents from you have a stinky breath *-*
- it helps with back-pain, headaches, heart health...etc
- it helps boost your immune system
- increases your brain power
so those are what i got for you about why water is important to us :D
Answer:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is 
.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 104 kPa
= final pressure of gas = 52 kPa
= initial volume of gas = 
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
